That's my problem with the debate: people like you seem very proud to be uninformed. It exists as much as end-to-end encryption exists. It's cryptography, it's not up to debate.

But people who have no clue are very vocal about their belief that it does not exist.

I also am not aware of any, do you have any examples?

There are no active implementations that do not suffer from severe issues.

There are two ongoing implementations: one weaker in the EU boooo and one good in Switzerland. None having severe issues. Questions?

I have none, I already am aware of the functioning of the systems that have been deployed, hence my statements of fact.
